Send bulk SMS in India without the DLT headache. BLACKSMS provides the simplest bulk SMS experience — instant setup, free trial, REST API, and India's lowest rates.
TRAI's DLT (Distributed Ledger Technology) regulation requires businesses to register their company, sender IDs, and SMS templates before sending promotional bulk SMS. This process can take days or weeks — a frustration for startups and small businesses.
BLACKSMS solves this in two ways:
For OTP, 2FA, and login verification SMS — no DLT registration required. Start sending immediately after signing up.
For promotional bulk SMS campaigns, BLACKSMS provides pre-registered templates and helps you with DLT setup — the fastest path to compliance.
All prices include GST. No hidden charges.
